Remark 1
The higher frequency range applies at 80 MHz and 800 MHz.
Remark 2
These guidelines may not be applicable in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection by
buildings, objects and persons.
1. The field strengths of fixed transmitters, such as base stations of
radiotelephones and mobile agricultural radio broadcast services,
amateur radio stations, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. A site
survey is recommended to assess the electromagnetic environment
due to fixed RF transmitters. If the measured field strength in the
location in which the UNIT is used exceeds the applicable RF
compliance level specified above, the UNIT should be observed to
verify normal operation. If unusual performance characteristics are
observed, it may be necessary to take additional measures such as
reorientation or repositioning of the UNIT.
2. Over the frequency range 150kHz to 80 MHz, field strengths should
be less than 3 V/m.
